About The Data

The bulk of the data we used came from the Free Law Project, which maintains a database of more than 35,000 financial disclosure records for federal judges, justices and magistrates, most of it dating back to 2003. These disclosures, which federal employees are required to file each year under the Ethics in Government Act of 1978, are maintained by the Administrative Office of the U.S. Courts. The law, however, requires most of them to be destroyed after six years, making many disclosures from earlier years hard to find. Our disclosures cover most of those filed since 2003, as well as some financial information disclosed by some justices during their Senate confirmations in 1990, 1991 and 2000. (Do you have information about a Supreme Court justice’s finances from before 2003? Email us.)

Because much of the data was extracted from PDFs using optical character recognition, we designed our own database and imported and cleaned the Free Law Project’s data to fix scanning and other errors. We corrected spelling errors, edited fields for style and clarity and, where possible, attempted to add contextual information by, for example, categorizing organizations and transactions, standardizing certain fields, updating entity names or filling in missing information.

In some cases, such as when the Free Law Project did not have a specific disclosure or had not extracted data from a report, we extracted or transcribed the data manually.

After cleaning and standardizing the data, we spot-checked it for accuracy, looking primarily for transcription or categorization errors. If you believe you see an error in the database, please contact us at [email protected].
